Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of silica aerogel powder detection, and specifically to a silica aerogel powder detection device and an operation method thereof. Background Art
[0002] Silica aerogel powder has a heat insulation function. When detecting the heat insulation function, a heating table is required. The surface of the heating table is flat and there is no obstruction around it. After a water droplet lands on the silica aerogel powder, the silica aerogel powder will fly out, resulting in the need to clean the area around the heating table after detection. Moreover, since the heating table does not have a weighing function, the heat insulation effect of the silica aerogel powder can only be observed with the naked eye. It is very difficult to tell whether the water has decreased or by how much as the heating time extends with the naked eye. Because the better the heat insulation effect of the silica aerogel powder, the more water remains, and the worse the heat insulation effect, the less water remains. Summary of the Invention
[0003] The purpose of the present invention is to provide a silica aerogel powder detection device and an operation method thereof, so as to solve the problems raised in the above background art that the heating table for the existing silica aerogel powder heat insulation detection is prone to fly out silica aerogel powder, the flying powder dirties the area around the detection heating table, and moreover, due to the lack of a weighing device on the heating table, it is impossible to accurately understand the heat insulation effect of the silica aerogel powder.
[0004] To achieve the above purpose, the present invention provides the following technical solutions:
[0005] A silica aerogel powder detection device and an operation method thereof, including a metal plane.

[0012] As a further description of the above technical solution:
[0013] The part of the heating strip located below the concave surface of the metal arc is concave in an arc shape.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] Embodiment:
[0035] Please refer to Figures 1-4 , the present invention provides a silica aerogel powder detection device, including a metal plane 1, the metal plane 1 is square-shaped, a metal arc concave surface 2 is formed by concave in the center position of the metal plane 1, a heater housing 3 is fixedly installed outside the metal plane 1, a heat insulation ring 4 is fixedly installed outside the top of the heater housing 3, an outer square ring 5 is fixedly installed outside the heat insulation ring 4, a protective plate 6 is movably installed on each surface of the outer square ring 5, a weighing device 7 is fixedly installed at the bottom of the heater housing 3, an electric heater 8 is fixedly installed in the inner cavity of the heater housing 3 near the metal arc concave surface 2, a column 9 is fixedly installed on the side of the electric heater 8, and the column 9 is fixedly connected to the bottom of the heater housing 3.
[0036] Specifically, as Figure 3As shown, a layer of metal skin is attached to the side of the outer square ring 5, and magnetic surfaces are symmetrically arranged on the movable side of the guard plate 6. The magnetic surfaces correspond to the position of the metal skin, and the guard plate 6 is convenient to fix.
[0037] Specifically, as Figure 1 and Figure 2 shown, the electric heater 8 includes an insulating and heat-insulating outer ring and heating strips. The heating strips are installed at intervals on the inner side of the insulating and heat-insulating outer ring. The column 9 is supported and fixedly installed at the position of the insulating and heat-insulating outer ring. The part of the heating strip located below the metal arc concave surface 2 is arranged in an arc concave shape, and the metal plane 1 and the metal arc concave surface 2 are heated evenly.
[0038] Specifically, the depth of the metal arc concave surface 2 is 5 mm - 10 mm. The depth is shallow, the opening is large, it is easy to clean, and the surface on which the silica aerogel powder can be spread is larger.
[0039] Specifically, the height of the guard plate 6 is 5 - 7 cm, and the height is sufficient.
[0040] Working principle:
[0041] Connect the power cord connected to the electric heater 8, and then the electric heater 8 heats the metal plane 1 and the metal arc concave surface 2. The heat-insulating ring 4 blocks the high temperature transmitted from the metal plane 1, and then the guard plate 6 is not affected by this high temperature, and the hand will not be scalded when touching the guard plate 6. When the temperatures of the metal plane 1 and the metal arc concave surface 2 rise to 160 degrees, first drop a few drops of water separately at the position of the metal plane 1 or the metal arc concave surface 2. If the water touches the surfaces of the metal plane 1 and the metal arc concave surface 2, it will evaporate quickly, indicating that this is the appropriate condition for detecting the heat-insulating function of the silica aerogel powder;
[0042] After the surfaces of the metal plane 1 and the metal arc concave surface 2 are dried, turn the guard plate 6 upwards, and the outer square ring 5 and the guard plate 6 are adsorbed and fixed to form a protective edge. Then sprinkle a layer of silica aerogel powder on the metal arc concave surface 2. The weight on the weighing device 7 changes, showing the weight of the silica aerogel powder. Then drop some water on the silica aerogel powder. The weight on the weighing device 7 changes, showing the total weight of the silica aerogel powder and water. When the water drops on the silica aerogel powder, part of the silica aerogel powder flies out and is blocked by the guard plate 6, and it is still within the weighing range of the weighing device 7;
[0043] Wait for 3 - 5 minutes. If you want to extend the detection time, it is also possible. After the waiting time, through the weight change on the weighing device 7, understand the water loss situation. The more water is lost and the faster the speed, the worse the heat-insulating effect of the silica aerogel powder. The less water is lost and the slower the speed, the better the heat-insulating effect of the silica aerogel powder;
[0044] After the detection is completed, wait for the surface temperatures of the metal plane 1 and the metal arc concave surface 2 to drop, and then wipe the metal plane 1, the metal arc concave surface 2 and the guard plate 6 with a clean cloth.
[0045] The embodiment of the present application also discloses a detection operation method for silica aerogel powder, adopting the following technical solution:
[0046] A detection operation method for silica aerogel powder,
[0047] The operation steps are as follows.
[0048] S1. The electric heater 8 heats the metal plane 1 and the metal arc concave surface 2, flips the guard plate 6, and the outer ring 5 and the guard plate 6 are adsorbed and fixed. After the temperatures of the metal plane 1 and the metal arc concave surface 2 rise to 160 degrees, drip water at the position of the metal arc concave surface 2. The high temperature causes the water to evaporate immediately, which is qualified.
[0049] S2. After the water dries, sprinkle the silica aerogel powder at the position of the metal arc concave surface 2, and drip water again at the position of the silica aerogel powder. The water remains in a liquid state and does not evaporate violently, which is qualified for detection.
[0050] S3. After 3 - 5 minutes, understand the reduction change of water through the weight change of the weighing device 7, and the time can be extended as needed.
[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
